# Stacking Sats on Kraken
|
||
|
||
First off: Here's to you, [Bittr](https://getbittr.com/) – you will be missed! 😢
|
||
|
||
This script is not a full replacement for the incredible service Bittr offered, but it's a start:
|
||
Automate your Stacking Sats process by regularly placing buy orders using the [Kraken API](https://www.kraken.com/features/api).
|
||
|
||
## ✋ Caveat
|
||
|
||
You need to install the dependency [kraken-api](https://github.com/nothingisdead/npm-kraken-api), which is a third-party package.
|
||
It has a minimal set of dependencies and I've done my best to audit its code.
|
||
Also the version is fixed, so that unwanted changes do not slip in.
|
||
|
||
However: Use this at your own risk and decide for yourself whether or not you want to run this script and its dependencies!
|
||
|
||
## 🔑 API Key
|
||
|
||
Obtain your Kraken API Key via [the API settings page](https://www.kraken.com/u/settings/api).
|
||
Generate a new API key dedicated for stacking using the "Query Funds" and "Modify Orders" permissions:
|
||
|
||
|
||
|
||
Only check the "Withdraw Funds" option if you plan to automatically withdraw Bitcoin from Kraken.
|
||
See details below.
|
||
|
||
## 📦 Setup
|
||
|
||
Prerequisite: At least the current LTS version of [Node.js](https://nodejs.org/).
|
||
|
||
Install the dependencies:
|
||
|
||
```sh
|
||
npm install
|
||
```
|
||
|
||
Setup the environment variables for the script:
|
||
|
||
```sh
|
||
# used to authenticate with Kraken
|
||
export KRAKEN_API_KEY="apiKeyFromTheKrakenSettings"
|
||
export KRAKEN_API_SECRET="privateKeyFromTheKrakenSettings"
|
||
# used for buying
|
||
export KRAKEN_API_FIAT="USD" # the governmental shitcoin you are selling
|
||
export KRAKEN_BUY_AMOUNT=21 # fiat amount you trade for the future of money
|
||
# used for withdrawal
|
||
export KRAKEN_MAX_REL_FEE=0.5 # maximum fee in % that you are willing to pay
|
||
export KRAKEN_WITHDRAW_KEY="descriptionOfWithdrawalAddress"
|
||
```
|
||
|
||
Use a dry run to test the script and see the output without placing an order:
|
||
|
||
```sh
|
||
npm run test:stack-sats
|
||
```
|
||
|
||
You should see something like this sample output:
|
||
|
||
```text
|
||
💰 Balance: 210000.00 USD / 21.0 XBT
|
||
|
||
📈 Ask: 21000.2 USD
|
||
📉 Bid: 21000.1 USD
|
||
|
||
💸 Order: buy 0.21212121 XBTUSD @ limit 21000.1
|
||
📎 Transaction ID: 2121212121
|
||
```
|
||
|
||
## 🤑 Stack sats
|
||
|
||
When you are good to go, execute this command in a regular interval:
|
||
|
||
```sh
|
||
npm run stack-sats
|
||
```
|
||
|
||
The best and easiest way is to wrap it all up in a shell script.
|
||
This script can be triggered via cron job, e.g. weekly, daily or hourly.
|
||
|
||
Here's a sample `stack-sats.sh` script:
|
||
|
||
```sh
|
||
#!/bin/bash
|
||
set -e
|
||
|
||
# hide deprecation warning
|
||
export NODE_OPTIONS="--no-deprecation"
|
||
|
||
export KRAKEN_API_KEY="apiKeyFromTheKrakenSettings"
|
||
export KRAKEN_API_SECRET="privateKeyFromTheKrakenSettings"
|
||
export KRAKEN_API_FIAT="USD"
|
||
export KRAKEN_BUY_AMOUNT=21
|
||
|
||
BASE_DIR=$(cd `dirname $0` && pwd)
|
||
cd $BASE_DIR/stacking-sats-kraken
|
||
result=$(npm run stack-sats 2>&1)
|
||
echo $result
|
||
|
||
# Optional: Send yourself an email
|
||
recipient="satstacker@example.org"
|
||
echo "Subject: Sats got stacked
|
||
From: satstacker@example.org
|
||
To: $recipient $result" | /usr/sbin/sendmail $recipient
|
||
```
|
||
|
||
Make it executable with `chmod +x stack-sats.sh` and go wild.

|
||
## 🔑 Withdrawal
|
||
|
||
Holding significant amounts on an exchange is never a good idea.
|
||
You should regularly take ownership of your coins by withdrawing to your own wallet.
|
||
This can either be done manually or it can be automated.
|
||
The script provided here will only withdraw to a previously defined Bitcoin address if the relative fees do not exceed a certain limit.
|
||
|
||
*It is optional to run the withdrawal script.*
|
||
|
||
### Example 1
|
||
|
||
- Max. relative fee: 0.5%
|
||
- Fixed Kraken fee: ₿ 0.00050
|
||
- Balance: ₿ 0.06000
|
||
➡️ No withdrawal since fee actual (0.83%) is too high
|
||
|
||
### Example 2
|
||
|
||
- Max. relative fee: 0.5%
|
||
- Fixed Kraken fee: ₿ 0.00050
|
||
- Balance: ₿ 0.12000
|
||
➡️ Withdrawal executed since actual fee (0.42%) is low enough
|
||
|
||
In case you plan to automatically withdraw from Kraken, a withdrawal method must first be defined.
|
||
If you already set up a methode you can reuse it.
|
||
Otherwise generate a new one by going to **Funding > Bitcoin (XBT) withdraw > Add address**.
|
||
The description field will later be used as an environment variable in the script.
|
||
|
||
To test the withdrawal of funds to your defined address run:
|
||
|
||
```sh
|
||
npm run test:withdraw-sats
|
||
```
|
||
|
||
You should see something like this:
|
||
|
||
```text
|
||
💡 Relative fee of withdrawal amount: 5.57%
|
||
❌ Fee is too high – max rel. fee: 0.50%
|
||
```
|
||
|
||
It is recommended to run the withdrawal script every time you stacked sats:
|
||
|
||
```sh
|
||
npm run withdraw-sats
|
||
```
|
||
|
||
Since it can take a couple seconds or minutes for your order to fill, you should run the following script a couple hours later after your `stack-sats` script.
|
||
Just set up a second cron job which executes the following script.
|
||
|
||
Here's a sample `withdraw-sats.sh` script:
|
||
|
||
```sh
|
||
#!/bin/bash
|
||
set -e
|
||
|
||
# hide deprecation warning
|
||
export NODE_OPTIONS="--no-deprecation"
|
||
|
||
export KRAKEN_API_KEY="apiKeyFromTheKrakenSettings"
|
||
export KRAKEN_API_SECRET="privateKeyFromTheKrakenSettings"
|
||
export KRAKEN_MAX_REL_FEE=0.5
|
||
export KRAKEN_WITHDRAW_KEY="descriptionOfWithdrawalAddress"
|
||
|
||
BASE_DIR=$(cd `dirname $0` && pwd)
|
||
cd $BASE_DIR/stacking-sats-kraken
|
||
result=$(npm run withdraw-sats 2>&1)
|
||
echo $result
|
||
```
|
||
|
||
Make it executable with `chmod +x withdraw-sats.sh` and add it to your cron schedule.
|
||
|
||
## ⚡️ RaspiBlitz Integration
|
||
|
||
This script ships with the [RaspiBlitz](https://github.com/rootzoll/raspiblitz) (v1.6 and above).
|
||
|
||
You can enable it via the Console of your RaspiBlitz.
|
||
Leave the main menu via the last option "Console" and use the following commands:
|
||
|
||
```sh
|
||
# enable the script
|
||
./config.scripts/bonus.stacking-sats-kraken.sh on
|
||
|
||
# switch to the stackingsats user
|
||
sudo su - stackingsats
|
||
|
||
# edit your configuration (see "Setup" above)
|
||
nano /mnt/hdd/app-data/stacking-sats-kraken/.env
|
||
|
||
# follow the instructions from the first step to set up a cronjob
|
||
crontab -e
|
||
```
|
||
|
||
Here is an example for a daily cronjob at 6:15am ...
|
||
|
||
```sh
|
||
SHELL=/bin/bash
|
||
PATH=/bin:/usr/sbin:/usr/bin:/usr/local/bin
|
||
15 6 * * * /home/stackingsats/stacksats.sh > /dev/null 2>&1
|
||
```
